Testing oVirt...

Is this an all in one?
-
@stacksofplates Are you asking about the hardware or the oVirt setup?

Any real advantage vs plain KVM?

oVirt is more in line with RHEV. If all you want to do is run VMs, a plain KVM setup is a simple.

@francesco-provino This is a 3 + 1 node hyperconverged cluster with Gluster, HA, Live Migration etc!

Very good more pics and stuff please, did you face any hosts disconnections I faced that alot

That's what I was wondering. I didn't know if it was a self hosted engine (couldn't think of the name last night) or multiple node setup.

This setup uses the Hosted Engine.

No host disconnections at all.
The current version (4.2.5) is very easy to setup.
I will post some pics of an upcoming version, oVirt Node (4.3) based on Fedora 28. -
oVirt Node v4.3 (based on Fedora 28) - this is pre-release:

So you're saying ovirt is pushing the Xen guys to get into gear as this appears to be the entire package, with FOSS.

I believe oVirt is being billed as "vSphere for FOSS"
You're probably not going to move the Xen/XS/XCP-ng guys off their spot.

Can we use the oVirt system to manage an existing KVM server?
( I want to try oVirt, but really don't want to wipe out the system I currently have set up ) -

( I want to try oVirt, but really don't want to wipe out the system I currently have set up )I tried setting up oVirt a few versions ago and from what I could find, it's almost expected you have a minimum of 3 physical hosts for it.
So no, you won't be able to manage a standalone KVM server since everything has to get built to be managed by the oVirt Engine.

Let us talk about Gluster, how do you feel safe with it ?
saw you choose an option with RAID 6, i dont get that cause from my trial, I make RAID and group disks then create Gluster volume from those mdraid volume, but it seems you did RAID 6 afterwards, hmm whats the logic behind that ?
What type of Gluster volume are you using, just distributed ?
I m still learning HCI so thus the beginner vibe

Scaling KVM basically, if you have 1 or 2 KVM servers thats fine, but if you want more you need better management that logging in each one.

No RAID6, I'm using RAID10.
Gluster volume is Replicate + Arbiter
This is a good blog post to get you started: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluster-storage/

You can now do a single host w Gluster:
